IM'P ROlI E M E N T l N PEG-FLOATS.

Specification forming part of Letters Patent No. 1 88,035, dated March6, 1877; application filed 'January 23, 1877.

Be it known that I, AMOS WHITTEMORE, of

, Gambridgeport, in the county ofMidd'lesex and State of Massachusetts,haveinvented certain new and useful lmprovements in Pe'g-Trim mers; andI do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains'to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification, in which- Figure 1 represents aperspective View of my invention. Fig. 2 is a plan view of the cutters.Fig. 3 is a plan view of the guardplate, with its stud and perforationfor lubricating the interior of the case. Fig. 4 designates a bottomview of the cutter. Fig. 5 is a vertical longitudinal section of theupper portion of my improved device.

The nature of my invention consists, mainly, in cutting or trimming pegsin boots and shoes without injuring the leather, either of insole or theupper.

Prior to the invention which I shall hereinafter explain, rotatingknives or cutters were not guarded or provided with the shieldshereinafter explained.

The main object of my present invention is to combine with rotatingcutters rotating shields, which will prevent any possibility of cuttingthe leather, whether operating at the heel or toe, as will behereinafter explained; also, to employ certain devices, in combinationwith a rotating peg-trimmer, and a rotating guard therefor, which willallow the same to be rotated freely, and which will also allow freeaccess to the interior of the frame or case containing the drivingmechanism, for cleaning and lubricating the same. Other improvementswhich I have made will be fully set forth in the annexed specification,in which-- A designates a spindle, on the lower end of which is fixed apulley, A, driven by a belt, a. The lower end of this spindle may beprovided with an adjustable screw and a fixingnut. B is a foot-box,having a collar, 1), and which is adapted to receive within it thepulley A, and which is secured to a table or other substantialstructure. 0 designates a tube,

which incloses the spindle A, and which is tapped on a male screw, 0,formed on the lower end of a case, which 1 shall designate by the letterD, and which constitutes the main frame of my device. This case is setat an obtuse angle with respect to the vertical axis of the spindle A,and the angle may be varied at pleasure.

The case which I above refer to is suitably recessed to receive toothedwheels; and it is also constructed with flanges d, and an intermediatecontracted portion, d, thus allowing a cap or cover, E, for the saidcase to be secured in its place by screws set in from below. The objectof thus constructing the case and securing its cap or cover upon it is,that in the event of any one or more of the screws becoming loose theywill not in any manner interfere with or injure the cutters. I

On the upper end of the spindle A is applied a bevel spur-wheel, e,which is supported on the upper end of a tube, F, and which engages witha bevel-wheel,f, on a cog-wheel, Gr. Both wheels f and G are journaledin the upper and lower sections of the case D, as indicated by Fig. 5.The cog-wheel G engages with the teeth of a cog-wheel, G, on afoot-spindle, g, alongside of an oil-receptacle, h, which is supplied aswill be hereinafter described. The upper journal 73 is tubular andscrew-tapped, and it affords not only a medium through which oil can befed to the gearing inside of the case D, but it also serves to receive ascrew, j, which assists in holding cutters J to and upon the plate L, asillustrated in Fig. 5. L designates a plate, which is fixed to and turnswith the journal 2'. This plate L is circular in its general outline,and constructed with raised guards or shieldsm on its periphery, whichhave laterally-rounded edges. Between the guards or shields m the plateL is scored out to allow a free discharge of the chips while trimmingpegs.

J designates a rotating peg-trimmer, having beveled cutting-edges 11.formed on its limbs or leaves 1). This cutter has also a convex topsurface, (shown in Fig. 5,) and it is held in its place on theguard-plate L by means of the screw 7', and also a stud, q, which latterenters one or the other of a number of holes, 8. (Shown in Fig. 4.) Theposition of the limbs p of the cutter with respect to the shields m isshown in Figs. 1, 2, and 3, wherein it will be seen that the front endsof the shields are slightly in advance of the outer termini of thecutting-edges n, and also that the highest edgesofthe shields areslightly above the outer ends of the limbs 12. By these means it will beimpossible to cut the insole or the upper-leather of boots and shoeswhile trimming off the pegs therein. The stud q and the holes 8 allowthe trimmer J to be adjusted and set forward to compensate for thereduction of the limbs p by sharpening. The hole t through theshield-plate L and the holes 0 1; through the cap E of case D allow oilto be supplied to the gearing inside of this case without the necessityof removing the cap.

The advantage of the rotatory cutters, in combination with the rotatoryshields, is that the chips will escape freely, and not clog the cutters;also, I can operate with less liability of cutting the upper-leather.

Having described my invention, I claim 1. In combination with rotatingcutters J, rotating guards or shields m, substantially as described.

2. Rotating cutters J, in combination with the rotating plate formedwith shield m, and scored as shown.

3. The removable rotating cutter J, in combination with the plate L andshields m, of segment form, substantially as shown.

4. Cutters J, which rotate with the plate L, in combination with stud qand holes 8, as set forth.

5. The shield-plate L, perforated at t, in combination withgear-casecover E, provided with the perforations v, as and for thepurposes set forth.

6. In combination with rotating cutters J aud rotating shieldplate L,the gearing G, G, f, and 1;, applied in a gear-case, D, which is set atan angle with respect to the spindle A, substantially as described.

In testimony that I claim the foregoing as my own invention I aifixmysignature in presence of two witnesses.
